摘要
开关磁阻(SR)电机具有结构简单、容错性好等优点,在矿业领域具有较好的应用前景。为提高SR电机的转矩性能,分析其转矩脉动情况,对角度位置控制运行方式下的电机导通角优化控制进行研究。建立了1台四相8/6极SR电机的有限元仿真模型,并对其转矩特性进行仿真研究,验证了角度位置优化控制的可行性和准确性。研究结果可用于指导矿用SR电机调速系统的设计和优化。
Switched reluctance （SR） motors incorporate the merits of simple structure and muit tolerance, having a bright future in the mining applications. To improve torque performance of SR motors, its torque ripple is analyzed, thus proposing an optimal control strategy of SR motor in the angle position control mode. A finite-element analysis model is developed for a SR motor, and it is used to predict the torque performance of motor. Thus, the validation and the accuracy of the proposed control s trategies are verified. The research results lay a foundation for design and optimal control of SR motor drive.
